Thanks for coming into to this postI want to use ADC which is embedded in STM32G030J6M6.I had a experiment with a STM32F030F4 which showed me a very clear ADC.So I used a exactly same source code except ADC and GPIO settings.But I got a unstable ADC ...

I'm trying to use ADC in stm32g030j6m6 to measure DC voltage.but, whenever I try to make experiences. I found out that under 3V, The accuracy of adc isn't great. It has a 10% error.​I attached source code that I used in my experience and the table th...
